Bastioned Tarragon

#0a610e
Notes

Bastioned Tarragon (#0A610E) is a deep green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (123°, 81%, 21%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bastioned
adjective

Italian bastionato, fortified-with-bastions — past-participle of bastion, derived from bastia (fortified-tower). As a color modifier, bastioned implies a saturated-and-fortified-and-projecting quality, the deep-rich color of Vauban-period military-fortress star-fort projecting-bastion stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Tarragon
noun

Artemisia dracunculus, the French tarragon — small narrow-leaved relative of wormwood whose volatile oil tastes faintly of anise. The color refers to fresh tarragon leaves on the stem: a saturated, slightly muted green with the matte finish of a Composite-family leaf surface. Cooler than basil, lighter than spinach, with the kitchen specificity of a herb that defines béarnaise and a French roast chicken.
